The correct acronym is ARP and it stands for Automotive Racing Products.

Sorry, same shit, different badge. Everytime I see a tubular mani on a dsm, I think "dn performance" because they all crack and creep.


The welds are slightly better (cosmetically) on a DN, but in the end it will crack.

You guys, try to be nice to the noob. He is a nice guy, just isn't well versed in "internet" presense.

Can you explain how manifold choice relates to boost creep? I see zero correlation between the two.

Well you don't because you don't do this for a living.

Most tubular manifolds I have seen on dsm's have creeped. All I can think of is it would be an efficency issue, to where the runners are pointed towards the turbine wheel differently and it is more difficult for the wastegate to expel exhaust energy, just a theory.
I've seen it 3 times now, all 3 times had different turbo's, different exhausts, different boost controls, different 02 housings...all yield to a slight creep in boost as rpm goes up. The only common links have been the "tubular" cheap manifolds.
Maybe it has just been random circumstances...but I doubt it.

It isn't anything bad, just creeps to more than what is normally manageable/obtainable at redline.
